media: uapi: h264: Increase size of DPB entry pic_num
DPB entry PicNum maximum value is 2*MaxFrameNum for interlaced
content (field_pic_flag=1).
As specified, MaxFrameNum is 2^(log2_max_frame_num_minus4 + 4)
and log2_max_frame_num_minus4 is in the range of 0 to 12,
which means pic_num should be a 32-bit field.
The v4l2_h264_dpb_entry struct needs to be padded to avoid a hole,
which might be also useful to allow future uAPI extensions.
